Objective To measure the equity of resources allocation in obstetric healthcare in Zhejiang Province, and provide evidence for decision making by healthcare departments of the government. Methods Lorenz curve and Gini coefficient were used to measure the equity of obstetric healthcare resources. Results The investigation found such allocation as equitable as measured by the layout of the number of live births, as the Gini coefficient of the distribution of obstetric doctors, nurses and beds was 0.1697,0.1971 and 0.1497 respectively by total birth, failing within the equitable range. However, when measured by geographic distribution, such coefficient were 0.2701, 0.3216 and 0.3341 respectively in cities, which were less equitable yet still within equitable range. Conclusions The government and health bureaus are recommended to scientifically predict the number of immigrants and rationally deploy healthcare resources according to the service radius of healthcare resources;moreover, more gynecologic doctors and nurses should be trained to improve the human resource structure in gynecologic departments. These effort can cater to the growing healthcare demands of the society resulting from a growing population of immigrants.

Conus textile is a kind of highly toxic and abundantly existing conus in the South China Sea. The toxin from C.textile could act on sodium channels(δ-conotoxins)and calcium channels (ω-，ε-conotoxins), respectively. Their specific chemical structure and biological activity have attracted a lot of attention in recent years. This article briefly reviews their biochemical characteristics, isolation, gene cloning, biological and neuropharmacological activities, as well as their potential applications.

Objective To investigate the effect of stress dose glucocorticoid on patients with acute respiratory distress syndrome (ARDS) combined with critical illness-related corticosteroid insufficiency (CIRCI).Methods All early ARDS patients combined with CIRCI were screened by an adrenal corticotrophic hormone (ACTH) test and randomly divided into treatment group (hydrocortisone 100 mg intravenous,3 times/day,consecutively for 7 days,n =12 ) and control group (equivalent normal saline,n =14 ).General clinical data,changes of arterial blood gas,hemodynamics and respiratory mechanics were observed and recorded at admission and at 7 days after treatment.Ventilator-free and shock-free days,ICU stay within 28 days after admission were recorded and 28-day mortality was used as judge prognosis index.Results CIRCI rate in 45 early ARDS patients was 57.8％ ( 26 patients),and the shock rate was markedly higher in ARDS patients with CIRCI than patients without CIRCI (46.2％ vs 5/19 ).There were no significant differences in baseline parameters,oxygenation and illness severity between the treatment and control groups,except for markedly lower lactic level in the treatment group [ 2.7 ( 1.2,3.9 ) mmol/L vs 4.6 ( 2.5,6.3 ) mmol/L,P ＜ O.05].After 7 days of treatment,PaO2/FiO2 markedly increased,while heart rate obviously decreased in the both groups.Compared with the control group,survival time of patients was significantly longer and shock rate of the patients was markedly lower in treatment group within 28 days (5/12 vs 10/14,P ＜ 0.05).The 28-day mortality,which were adjusted by baseline arterial lactic,was lower in the treatment group (2.6/12 ) than in the control group (5.8/14) while with no significant difference ( P ＞ 0.05 ).There was no significant difference in complication incidence between the two groups.Conclusion Stress dose glucocorticoid could reduce shock incidence and prolong survival time,and has a tendency of lower 28-day mortality in early ARDS patients combined with CIRCI.

Objective To investigate the effects of extracorporeal membrane oxygenation (ECMO) on survival of adult from acute respiratory distress syndrome (ARDS). Method We searched Pubmed, Embase, Cochrane Library, Web of Science databases to find relevant literatues on ECMO in treatment of ARDS, which are reported from January 1966 to June 2010. Meta analyses was performed. Results Three papers about randomized controlled trial (RCT) of evaluating ECMO in patients with severe ARDS were enrolled for analyses. Meta-analysis of the three randomized controlled trials revealed ECMO did not decrease the mortality of ARDS patients. However, the cumulative meta-analysis of randomized trials showed ECMO had a protective effect on patients with ARDS. The most recent observational studies suggested that ECMO significantly decreased the mortality of ARDS caused by H1 N1 viral pneumonia. Conclusions There is no evidence to prove the benefit of ECMO in patients with ARDS. However, ECMO should be considered to use in early stage of ARDS as a last rescue resort for potentially reversible severe acute respiratory failure. Further investigation of large sample of high quality RCTs is needed.

ObjectiveTo compare the outcomes of 3 modes of weaning,e.g.SmartCare (a computerdriven knowledge-based system),spontaneous breathing trials (SBBT) and empirical methods,used in patients with chronic obstructive pulmonary diseases (COPD) weaned off mechanical ventilation.MethodsSixty-eight COPD patients were enrolled and randomly (random number) assigned to receive SmartCare (SC group,n =24),SBT (SBT group,n=24) or empirical methods (EM group,n =20).The following data were recorded including beginning of weaning:time consumed for weaning,duration of mechanical ventilation,length of ICU stay,success rate of weaning,survival rate during hospitalization and the complications of mechanical ventilation.The patients were considered as successfully weaned when they were able to tolerate at least 48 consecutive hours of spontaneous breathing.ResultsTime required for weaning and total time for mechanical ventilation in SC group were greatly shorter than those in EM group (P =0.002,0.002),but there were no differences between SC group and SBT group (P =0.540,0.573).Though the length of ICU stay (7.5 d) in SBT group was notably shorter than that in EM group (82.5 d) (P=0.015),there was no difference between SBT group and SC group (8.0 d).Weaning success rate was greater in the SC group (88.3％) than that in EM group (50.0％),but there was no difference between SBT group (66.7％ ) and SC group.No significant differences in survival rate during hospitalization,rate of re-intubation,self-extubation and need for noninvasive ventilation were found among three groups.ConclusionsCompared to empirical methods for weaning,SmartCare could greatly increase the success rate of weaning,but it was not superior to SBT.

Objective To evaluate the effect of sucralfate and acid-suppressive drugs on preventing ventilator-associated pneumonia (VAP) in mechanically ventilated patients.Methods All randomized controlled trials (RCTs),which studied the effect of sucralfate and acid-suppressive drugs on the incidence of VAP in mechanically ventilated patients,were searched from PubMed,Embase and the Cochrane Library during January 1966 to March 2013 via manual and computer retrieval.All related data were extracted.Meta analysis was conducted using the statistical software RevMan 5.2 and the quality of the RCTs was strictly evaluated with the methods recommended by the Cochrane Collaboration.Results A total of 15 RCTs involving 1315 patients in the sucralfate group and 1568 patients in the acid-suppressive drug group were included in this study.The incidence of VAP was significantly reduced in the sucralfate group (RR =0.81,95％ CI 0.7-0.95,P =0.008),while no difference was found between the two groups in the incidence of stress-related gastrointestinal bleeding (RR =0.96,95％ CI 0.59-1.58,P =0.88).No statistical difference was found in the days on ventilator,duration of ICU stay and ICU mortality in the two groups (all P values ＞ 0.05).Conclusion In patients with mechanical ventilation,sucralfate could decrease the incidence of VAP,while has no such effect on the stress-related gastrointestinal bleeding,the days on ventilator,duration of ICU stay and ICU mortality.

Objective To observe the expression of I-Ab/I-E on circulating,lung and splenic dendritic cells (DC) in acute lung injury (ALI) mice.Methods Twenty-four C57BL/6 mice were randomly divided into four groups:control group,ALI 6 h,ALI 12 h and ALI 24 h group.Blood,lungs and spleens were harvested after lipopolysaccharide or phosphate butter solution administration.The expression of I-Ab/I-E on DC was assessed by flow cytometry (FCM).IL-6 level in the lung was measured by enzymelinked immunosorbent assay (ELISA).Lung wet weight/body weight (LW/BW) was recorded to assess lung injury.Meanwhile,pathological changes were examined under optical microscope.Results (1) lipopolysac charide-induced ALI mice resulted in a significant increase in lung LW/BW ratio.(2) Histologically,widespread alveolar wall thickening caused by edema,marked and diffuse interstitial infiltration with inflammatory cells,and severe hemorrhage in the interstitium and alveolus were observed in the ALI groups.(3) The level of IL-6 in lung tissue was significantly enhanced in ALI mice.(4) FCM analysis showed that I-Ab/I-E expressions on lung DC [(73 ±9)％],and splenic DC [(81 ±8)％] were significantly higher than that on circulating DC [(24 ± 7) ％ ; P ＜ 0.05] in control mice.(5) In ALI mice,the expressions of I-Ab/I-E on peripheral blood DC were (34 ± 17)％ at 6 h,(51 ± 16)％ at 12 h,(50 ± 17)％ at24 h respectively; I-Ab/I-E expressions on lung DC were (82 ± 14)％ at 6 h,(88 ±6)％ at 12 h,(90 ±10)％ at 24 h respectively; the expressions of I-Ab/I-E on splenic DC were (88 ± 8)％ at 6 h,(89 ± 4)％ at 12 h,(93 ± 9)％ at 24 h respectively,which were also significantly higher than those on the peripheral blood DC (P ＜ 0.05).(6) The I-Ab/I-E expressions on circulating DC in ALl mice at 12 h and 24 h was significantly higher than that on circulating DC in control mice (P ＜ 0.05).(7) The I-Ab/I-Eexpressions on lung DC and splenic DC in ALI mice at 24 h were significantly higher than those on lung DC and splenic DC in control mice (P ＜ 0.05).(8) There was a significant correlation of I-Ab/I-E expression on respiratory DC with the IL-6 level and lung injury score in LPS-induced ALI group (P ＜ 0.05).Conclusions There is a dynamic characteristic in the expression I-Ab/I-E on circulating,lung and splenic DC populations in ALI mice.I-Ab/I-E on pulmonary DC seems to play an important role in the pathogenesis of ALI.

Objective To verify the targeting regulatory relationship between microRNA -939 (miR -939) and CD2 -associated protein (CD2AP).Methods The online RegRNA software was used to predict the human CD2AP promoter for potential binding sites complementary to miR -939.HEK -293T cells were cotransfected with hu-man CD2AP promoter plasmid pGL3 -2K and microRNA negative control (miR -NC)or miR -939 mimics,and the relative luciferase activity(RLA)was detected at 24 h post -transfection.HEK -293T cells were transfected with miR -NC or miR -939 mimics for 48 h,and the CD2AP mRNA expression level was detected by adopting reverse tran-script and real -time fluorescence quantification -PCR,while the CD2AP protein expression level was detected by using Western blot.Results (1 )There were 2 miR -939 binding sites at CD2AP promoter region,located at -468 to -491 and -654 to -677 upstream of initiation codon ATG (marked as +1 )relatively.(2)At 30 nmol/L,50 nmol/L,the RLA in miR -NC group and miR -939 group were 6.81 ±0.88 vs 6.07 ±2.24,5.88 ±1 .44 vs 3.94 ± 0.79 relatively,and there were no significant differences between the 2 groups (t =3.04,2.06,all P >0.05),while the RLA between the 2 groups were 5.58 ±0.58 vs 3.29 ±0.64 at 1 00 nmol/L,and the difference was significant between the 2 groups(t =4.07,P <0.05).(3)At 30 nmol/L,50 nmol/L and 100 nmol/L,the relative CD2AP mRNA expression in miR -NC group and miR -939 group were 1 .00 ±0.01 vs 0.80 ±0.08,1 .00 ±0.00 vs 0.80 ±0.1 3 and 1 .00 ± 0.00 vs 0.72 ±0.07 relatively,while the CD2AP mRNA expression was decreased by 20% -30% at each concentration level,and there were significant differences between the 2 groups (t =4.44,2.93,6.84,all P <0.05).(4)At 50 nmol/L, the relative CD2AP protein expression in miR -NC group and miR -939 group were 0.48 ±0.09 vs 0.19 ±0.12,and the CD2AP protein expression was decreased,and the difference was significant (t =3.36,P <0.05).Conclusions CD2AP is the target gene of miR -939,and miR -939 can down -regulate the expression of CD2AP both in mRNA and protein levels by targeting its promoter region,which indicates that miR -939 may mediate the podocyte injury.
